Effective contaminant removal for extended engine life – The OEM 186-1012240 Oil Filter is engineered to remove 99% of particles larger than 15 microns, ensuring clean oil circulation and protecting critical bearings and turbochargers. Designed for SINOTRUK Homan heavy-duty diesel engines, this spin‑on filter features a robust cellulose/synthetic media blend and a high-pressure bypass valve. For guaranteed compatibility and performance, always choose genuine Sinotruk Homan parts.
The 186-1012240 oil filter incorporates a silicone anti‑drainback valve to prevent dry starts and a coiled steel center tube for crush resistance. Its large filtering area (1.2 m²) provides high dirt-holding capacity, allowing extended drain intervals while maintaining engine protection.
The 186-1012240 oil filter uses a multi‑layer filtering medium consisting of cellulose fibers reinforced with synthetic microfibers. This blend achieves a beta ratio of β15 > 200 (99.5% efficiency at 15 microns), removing soot, carbon, and metallic wear particles before they can damage bearings or oil passages. The filter’s pleated design maximizes surface area, providing a dirt‑holding capacity of 55 grams (ISO 4548-12 test dust).
Unlike low‑cost aftermarket filters that use cardboard end caps, this genuine SINOTRUK Homan component features galvanized steel end caps bonded with heat‑resistant adhesive. The center tube is fabricated from perforated, coiled steel with a burst strength of 35 bar, ensuring structural integrity even during cold starts with high oil viscosity.
The built‑in relief valve (bypass valve) opens at 2.5 bar differential pressure, allowing oil to flow directly to the engine if the filter becomes clogged. This prevents oil starvation while still providing some filtration through the bypass channel. The anti‑drainback valve, made of silicone rubber, prevents dry starts by retaining oil in the filter when the engine is off.
β15 > 200 removes 99.5% of particles ≥15µ. Synthetic/cellulose blend resists oil degradation and handles extended drain intervals.
Silicone rubber remains flexible from -40°C to +150°C, preventing dry starts and reducing engine wear after long periods of inactivity.
Calibrated to open at 2.5 bar ±0.3 bar, protecting the engine from oil starvation while maintaining filtration under most operating conditions.

The 186-1012240 oil filter is manufactured using a fully automated assembly line that pleats, bonds, and encapsulates the media with zero human contact. The pleat depth and spacing are optimized to minimize pressure drop while maximizing dirt capacity. The result is a filter that consistently achieves a low clean pressure drop of ≤0.2 bar at nominal flow (120 L/min at 80°C oil temperature).
The silicone anti‑drainback valve is molded in‑place to prevent leakage; it is tested to withstand 50,000 cycles of opening and closing without deformation. Unlike nitrile rubber valves, silicone retains its shape and flexibility even after prolonged exposure to hot oil, eliminating dry start risk after overnight parking.
The outer can is made from 1.2 mm thick welded steel, coated with a durable epoxy finish that resists corrosion from road salt and moisture. The can is die‑stamped with the OEM number, production date, and batch code for full traceability. An internal pressure‑relief spring ensures that the bypass valve opens precisely at the specified differential.
The synthetic/cellulose media is impregnated with a phenolic resin that resists moisture degradation and maintains structural integrity even when saturated with sludge. The media is also treated with a surfactant that enhances oil flow while capturing fine particles. Independent laboratory tests confirm that the 186-1012240 outperforms leading aftermarket filters by 30% in dirt-holding capacity.
The nitrile rubber base gasket is designed for a single use; its dimensions are precisely controlled to ensure a tight seal on the filter head without over‑compression. A silicone‑based lubricant is pre‑applied to the gasket for easy installation and sealing.
The 186-1012240 oil filter is a direct replacement for the original filter on SINOTRUK Homan engines and many other heavy‑duty engines using M22 x 1.5 thread (standard for most diesel oil filters). The filter has an outer diameter of 102 mm and height of 175 mm, fitting all standard oil filter heads.
Installation is simple: apply a thin film of clean oil to the rubber gasket, spin the filter onto the oil filter head until the gasket contacts, then tighten an additional ¾ to 1 full turn by hand (never use a wrench to avoid over‑tightening). Torque specification is 20‑25 Nm if using a socket, but hand‑tightening is preferred.
1) Warm up the engine to operating temperature, then shut it off. Place an oil drain pan under the filter. 2) Use a strap or cup‑style filter wrench to remove the old filter. Be careful – the filter may be hot and full of oil.
3) Clean the filter head mounting surface with a lint‑free cloth. Inspect the old gasket to ensure it has not stuck to the engine. 4) Open the new 186-1012240 filter and apply a thin coat of clean engine oil to the rubber gasket. 5) Spin the filter onto the mounting stud until the gasket contacts the head, then tighten by hand an additional ¾ turn (approximately 20‑25 Nm).
6) Refill the engine with the specified amount of fresh oil, then start the engine. The oil pressure warning light should extinguish within a few seconds. 7) Shut off the engine and check for leaks around the filter gasket. Top up oil if necessary. 8) Record the filter change in the vehicle maintenance log.
The 186-1012240 oil filter should be replaced at every oil change, typically every 30,000 km for on‑highway trucks or 500 operating hours for off‑highway equipment. Use only genuine SINOTRUK Homan filters or reputable equivalents meeting OE specifications.
If the filter leaks after installation, check for a double gasket (old gasket stuck to the engine) or insufficient torque. Never use a wrench to overtighten – this can distort the seal. If the oil pressure warning light stays on after filter change, a clogged bypass valve or wrong filter could be the cause; verify with a mechanical gauge.
Cut open the used filter occasionally to inspect for metal debris – this can reveal early engine wear. Always dispose of used filters properly (drain oil, then recycle metal components).
The 186-1012240 oil filter is manufactured under IATF 16949 and ISO 14001 certified processes. Each filter is 100% leak‑tested with air pressure (3 bar) and 100% bubble‑point tested to verify media integrity. Random samples undergo multi‑pass testing per ISO 4548-12 to determine beta ratio and dirt holding capacity. Additional validation includes a 500‑hour thermal cycle test (-40°C to +150°C), a 20g vibration test (10-2000 Hz for 100 hours), and a 1,000‑hour oil flow endurance test at 15 bar.
The filter meets or exceeds OEM performance requirements for SINOTRUK Homan and complies with ISO 4548-1 (general specifications). A laser‑etched batch code on the can provides traceability. Counterfeit filters often use glued paper end caps, lack the silicone ADBV, and have less than half the dirt holding capacity. Always verify the QR code on the box.
A fleet of 800 SINOTRUK HOWO dump trucks in Australia switched from a major aftermarket filter to the 186-1012240 genuine filter. After 18 months, oil analysis results showed a 45% reduction in silicon and iron content, leading to bearing life extension of over 200,000 km. The fleet also reported fewer cold‑start knocking incidents due to the silicone ADBV.
Another user – a long‑haul carrier in Germany – extended oil drain intervals from 30,000 to 45,000 km after using genuine filters, based on oil analysis that confirmed the filter maintained efficiency even at extended mileage. The company saved over 25,000 euros annually in oil and filter costs.
Each genuine 186-1012240 oil filter is sealed in a shrink‑wrap sleeve and packed in a branded SINOTRUK Homan carton. The box includes a QR‑coded authenticity card and a plastic cap to keep the filter clean before installation. The filter can is printed with the OEM number, production batch, and holographic label.
Counterfeit filters often have faint printing, a missing silicone valve (or black nitrile rubber substitute), and a rough‑cut gasket. The genuine filter has a distinct deep can colour and a smooth, even coating. Always scan the QR code to verify on the SINOTRUK Homan portal. Using a fake filter can lead to engine damage from unfiltered oil, voiding the manufacturer’s warranty.
Summary: The SINOTRUK Homan Oil Filter (OEM 186-1012240) delivers exceptional filtration efficiency, high dirt‑holding capacity, and reliable bypass protection for heavy‑duty diesel engines. Protect your engine with this genuine OEM component – trusted by fleets and mechanics worldwide for cleaner oil and longer engine life.
